Which of the following is the most accurate definition of heritability? Select one: a. the amount of variation in a behavioural measure taken in a population that can be attributed to genetic variation among the members of that population b. the statistical likelihood that an individual will exhibit a phenotypic trait given the extent to which that individuals parents exhibit that trait c. the amount of variation in a behaviour that cannot be attributed to environmental factors d. the amount of variation in a phenotypic trait in a population that can be attributed to genetic variation among the members of that population

The heritability of a trait: (a) is the proportion of phenotypic variation in the population that is due to genetic differences between individuals (b) determines whether natural selection could result in evolutionary change (c) is the proportion of an individual's phenotype that is due to its genotype (d) a and b are correct (e) a, b, and c are all correct

Heritability relates to the a. percentage of a person's intelligence that is due to environmental influences. b. percentage of a person's intelligence that is due to genetics. c. correlation of intelligence test scores among family members. d. extent to which variability among individuals intelligence scores can be attributed to genetic variation. e. genetic stability of intelligence over time.
Heritability of intelligence refers to a. the extent to which a person's intelligence is caused by genetics. b. the effect of adoption on the intelligence of adopted children. c. the amount of group variation in intelligence that can be attributed to genetics. d. the extent to which the quality of schools and other environmental factors determine intelligence. e. the correlation between intelligence test scores of identical twins.
